It depends: As a rule we do not recommend a lot of soda intake. People with adhd do respond to stimulants including sodas with caffeine. However, the sugar in soda can contribute to inattention. If you use soda, try to use one that is sugar-free. In any event dentists know that the acids in soda, diet or not, are harmful to your enamel. Good luck with your journey.
